The rainy season is about to enter the north by the end of June, and there was no heavy rain this summer, which is considered a drought.

Originally, Chen Mu thought there would be no more heavy rain this year until winter, but now looking at the celestial phenomena, it may rain soon.

It rained. Since Chen Mu had a bird gun team in his hand, he hated the rain. Later, there were boats and cannons, and this was even more so.

Because it rained means that his subordinates' combat power has dropped sharply.

Without artillery or bird guns, his ability to command operations was greatly weakened because his tactics were born with firearms, otherwise even one general could defeat him in cold weapons combat.

Fortunately, what awaited him was not an encounter, but a defense, and it was also the riverbank bridgehead defense that he was more familiar with, and it was even more powerful than the conditions in the Battle of Xinjiang.

The Mama Refuge Water is long, but the Mama Refuge Water is also very wide. Although there are several uneven places in the water depth of less than half a person, most of them form river valleys between the mountain walls on both sides, and there is no road for Mongolian cavalry to pass through. There are only two real gaps.

One is to leave a Shuanma Bridge with a rear road of more than ten steps for the friendly troops in the front, and the other is fourteen miles northwest of Shuanma Bridge. Once it rains, the river water will rise from the source of the mountain, making it even more difficult for the enemy to cross the river there. Therefore, the mission of guarding is not difficult for the Four Thousand Flag Army.

What's more, between the two main roads, there are more than 4,000 flag troops fortified and stationed, and it only takes half an hour to set off from the mail cavalry to the army and the army to help.

The artillery position is a big operation. Twenty-four artillery pieces of different light and heavy will be placed directly behind the gunman's position. Chen Mu asked to build a solid earthwork that was one meter high, forty-four steps wide, and forty-long, and to build a gentle slope twenty steps behind it. A huge cannon must be installed up and down the slope.

The cannons are placed on the slope and the gunpowder is placed to cover the rain, and the bottom of the slope is to cover the rain. In this way, if the situation is not good, the artillery can bring the cannons to maneuver quickly first - but the degree of mobility depends on God's intention. Once the road is muddy, the cannons cannot run fast.

Fortunately, not far from the position is the Sanhe Tuguan Road. As long as you can walk there, even if it rains, the cannon carts can freely run.

In Chen Mu's design, the gunman trench is just a hundred steps in front of the artillery position, and is 80-step arc trench, which is five steps wide and four feet deep. It is made of wooden boards and large shields spliced ​​out of the incline from the back to the front. The wooden boards are supported by big sticks every two steps in front of the trench, and the board is covered with trench oil-soaked tent cloth.

In front of the trenches, a row of large shields are laid horizontally, and the rainwater is also placed obliquely to guide the outside, providing some protection and use of gunfire for the flag army.

Chen Mu named this Chen's rainproof trench and composed two pieces, one of which was handed over to the miner's head of his subordinates and asked Hu Daxiong to supervise their excavation of fortifications, and the other was sandwiched in a notebook for later sorting.

The miner is very useful. He had long wanted to establish a geoengineering army under his command, but was interrupted because Qi Jiguang transferred him to the north. However, Xu Jue recruited him a group of mine soldiers. Not to mention these people, the miner Chen Mu must recruit his own hands.

That is, relying on the large number of flag troops in hand, Chen Mu would not be able to build such a large project in a short period of time. However, local operations have only this benefit. People with a radius of more than ten miles help log and transport them. Of course, people who have been fleeing from Baoding were also intercepted to Fangshan for labor.

How does cement burn?

Limestone and clay milling surfaces are cooked and then paired with iron slag?

But Chen Mu didn't know the matching ratio, so he could only try it poorly. After recording it in his notebook, he sent a letter to the Nanyang Guard.

If this thing can be made, with bricks and stones, steel bars... can it be made of steel bars?

Don't worry if it can be done or not, let's try it first.

Even if it can be made, this thing is of no use in the north. Beilu can't even shoot the wooden walls, so he still has to use it in the south.

Later, he loaded more than a dozen ships of concrete and steel sticks, drove the boat to Malacca and Luzon and built the artillery tower, and built it side by side with the Portuguese and Spain fortress. At worst, the artillery fired each other to see who is strong!

What? Is this invasion?

No, no, if that happens, it must be a just war. For the sake of Mantaska and Luzon, there is no need to rename Malacca and the Philippines. Fighting for the honor of the tribute country was General Chen's lifelong pursuit.

But at the moment, he has to win this battle first, and even if there are no difficulties and create difficulties, he has to go.

He needed a beautiful victory to establish prestige among the three guards, and also a gorgeous enough military achievement to be promoted. Now Chen Mu seems that the Northern Transfer is no longer a bad thing, but he finds another breakthrough for him - a person who goes straight to the court and makes friends with the country and gains the power to open the maritime affairs in Nanyang.

If the matter of maritime affairs is too involved, it will hurt the interests of too many people. This is not something he can do alone and requires strong support.

Fortunately, there are at least two people in the cabinet who are determined to be self-reliant and take it as their mission to enrich the country and strengthen the army.

To be honest, Chen Mu now has a very understanding of the mentality of constantly building the Great Wall and bringing out a long line of defense. He talks on paper and knows more about it, and he is not sincere enough. He moves to defend Fangshan by himself, and he truly understands how difficult it is to guard against nomads in this era.

There is no Internet or telephone, war reports, and the police can still be transmitted by short-distance coastal defense like in Guangdong. However, in northern Xinjiang, it depends entirely on two or four legs, which is too slow.

Our messenger rode his horse and the enemy was also riding his horse. The governor received the war report to dispatch troops and generals. The troops set off from this side, and the enemy cavalry had already run to the other side and had another big plunder.

If you want to stop a ranger, you have to use several times the force in all directions to surround them. However, the distance between the troops and horses is different, and the location and time of sending troops is different. It is not easy to join the siege? I am afraid that the greater possibility is that before the encirclement has been formed, the enemy's faster mobilization and the superior forces are mobilized to divide them and attack them.

Over time, the young soldiers did not dare to fight, and the soldiers did not have time to fight, so it became such a weak situation. The movements of the Altan army were completely judged by the battle report of the fallen city. Before they could knock on the gate, the pass was ready to fight.

If he did not want his troops to come to the capital and only caused trouble to Shanxi, the Ming army would be helpless.

The sent with the baggage were also voices of peace talks rising in the court. In fact, most discerning people know that peace talks are the only way out. They have been arguing since April, and are still arguing. The debate is nothing more than using war to promote peace talks or money to promote peace talks.

No matter what, everyone is waiting for the outcome of the war, the difference is that some people need a victory.

Chen Mu was busy praying to the sky outside the military, praying that the Tumote tribe could rush to the Juma River, because the man who came out of the south stubbornly believed that the great victory that the world was waiting for would be created in his hands.

On September 7th, a sudden rain fell from the sky, and the Juma River surged. The victims affected by war on the other side of the river followed one after another. They brought news that the Northern Territory had passed through Jingxing and entered Zhending. At the same time, the Nanyang Guards also sent artillery to the capital for the second time, sending Bai Yuanjie about the Nanyang Guards' affairs, and also with a skin-like thing.

Chen Mu's short sword was nailed to the table with a soft object of unknown structure, and his expression was excited.
